Windows command prompt by default will launch without administrative privilege even if the user is an Administrator. You will get an access-denied error when running commands that require administrative privilege at the command prompt. 

C:\Users\user>net user newuser /add System error 5 has occurred. Access is denied.

To open the command prompt and run commands with administrator privilege, you need to run the Command Prompt app as administrator.
